7 7 Features of Stepping Motor Comparing to an induction motor A stepping motor has the following advantages compared to an induction motor. It is most suitable as an actuating drive for small mechanisms including control valves. High torque for small size (approx. 10 times greater than an induction motor of the same mass) High torque at startup; with little torque variation during acceleration Variable rotating speed Rotating speed unaffected by load changes High precision positioning by acceleration/deceleration control Unaffected by voltage or frequency variations by the power source Predictive control enabling the motor to stop without overshooting Basic rotating step per pulse of the two-phase stepping motor employed by the electric actuators is 1.8 degrees, thus requiring 200 pulses to complete a full 360-degree rotation. The exact number of pulses is controlled by a micro-processor. The Predictive Control employed as a part of its control algorithm enables the actuator to smoothly stop at an exact position (angle) without overshooting. Mechanism of Stepping Motor Damper Teeth 2 Teeth 1 Stator torque [N m] pulse frequency TIMES HIGHER STEPPING MOTOR INDUCTION MOTOR rotating speed [rpm] Decelerating toward the stop position Pulse frequency increasing quickly to achieve the preset max. speed The below illustrations show cross section images of a stepping motor, called also stepper motor or step motor. The stepping motor consists of two major components: a stator (stationary part) and a rotor (rotating part). The rotor is a permanent magnetic rotating shaft, surrounded by eight electromagnets or coils of two phases (A and B). Each electromagnet is energized in turn, attracting and repulsing the rotor to rotate its shaft. The motor shaft is connected to a damper that enhances the torque characteristics of the motor at high speed. How Stepping Motor Works The N pole and S pole toothed gears are engaged with an offset of half tooth. The bottom of a N pole tooth is aligned with the top of a S pole tooth. Each pulse moves the shaft by a quarter (1/4) tooth pitch while the N pole teeth and the S pole teeth are attracted and repulsed in turn. Each of those rotations is called a step. The motor has 50 teeth around the wheel, turning 1.8 degrees per step, requiring 200 pulses to make a complete rotation with an integer number of steps. In this way the motor can be turned by a precise mechanical angle in high resolution. The motor shaft rotates more than 100 times while the actuator travels the entire stroke/span. The calculated resolution is greater than 1/20000 (*). Teeth 2 S pole Teeth 1 N pole Rotor made of permanent magnet Teeth position offset by half tooth by each other 1/1000 Resolution (*) The nominal resolution described in the actuator data sheet is 1/1000, considering additional influencing factors such as the accuracy of the position detecting sensor, backlash of the reducing gear mechanism. 1 N 1 pulse N S Ball bearing S Shaft Stator Rotor time Simplified Stepping Motor Operation INITIAL STATE The example shows the rotor turning counterclockwise.

The above is a simplified example with 15 teeth. ers 7
